iDO-306 Online Fluorescence Dissolved Oxygen Sensor
iDO-306 Online integrated sensor is a luminescent dissolved oxygen physics of substances on the principle of excitation fluorescence quenching made based on the design. Blue light emitting diode (LED) in the emitted fluorescent substance on the fluorescent surface of the cap, the inner surface of the fluorescent substance is excited, emitting red light, by detecting the phase difference between the red and blue, and comparison with the internal calibration value to calculate the concentration of oxygen molecules, the temperature-compensated output automatically final value.
Without electrolyte, the polarization will not polarization
Without consuming oxygen, without affecting the flow rate
Built-in temperature sensor, automatic temperature compensation
Interference is not sulfide and other chemicals
Drift is small, fast response, more accurate measurement
Maintenance-free, long life cycle, the use of lower cost
Fluorescent cap replacement is simple
RS-485 interface, Modbus-RTUprotocol
